Who's got a Regal oil restrictor bolt and what exactly is the socket size for the head?
Ive got one here I bought off a member on here but cant seem to fathom out the head size
Will take a trip to Halfords tomorrow but thought Id ask on here first.
also on a side note what the hell is the 24mm socket for on the turbo fitment guide? cant recall using it the other week when "helping" someone fit theirs....
any help appreciated
